treeView keydown

[Hrvoje Voda]

What is wrong in this code?

private void tree_KeyDown(ob ject sender, System.Windows. Forms.KeyEventA rgs
e)

{

if (e.KeyCode == Keys.Enter )

{

ConnString = "workstatio n id=HRV;packet size=4096;integ rated
security=SSPI;d ata source=HRV;pers ist security info=False;init ial
catalog=DVD Kolekcija";

bDb = new Db(ConnString);

grid.Refresh();


grid.Table = bDb.datasetDVD. Tables ["DVD"];

}

}



I press ENTER when I'm on treeview control but nothing happens!

Re: treeView keydown

Hrvoje,

I would step through the code, and see if an exception is thrown
anywhere. If an exception is thrown, it will be swallowed by the code
calling your event handler, and do nothing.

Hope this helps.

Re: treeView keydown

Nothing is wrong with your code. Enter key is already used for an other
control (for example, if you set an accetButton for your form). The solution
is to says to the control that Enter key is an input key.

To do so, override TreeView class like following :
class TreeView2:TreeV iew {
protected override bool IsInputKey(Keys keyData) {
if (keyData==Keys. Enter) return true;
return base.IsInputKey (keyData);
}
}

Note that if you want to catch other keys like TAB, you can use a switch
statement. And if you want to catch ALL keys, always return true in
IsInputKey method.

And do not forget to replace
System.Windows. Form.TreeView tree;
par
TreeView2 tree;

et de même
tree=new System.Windows. Form.TreeView() ;
par
tree=new TreeView2();


Hope it helps,

Re: treeView keydown

I have a problem with overriding, because I'm using my user control.
I created some aditional functions for it, so when I put this code I can't
access my own functions!

Re: treeView keydown

If I have understood, you have already overloaded TreeView, so just put
IsInputKey method in your overloaded control.
If I didn't, show me your code.

Re: treeView keydown

I put IsInputKey method in my user control, but it still doesn't work!
Should I call it somehow in my other application?

Re: treeView keydown

In my application I have my user control and this code :

in constructor :

treeKolekcija.K eyDown += new KeyEventHandler (tree_KeyDown) ;



private void tree_KeyDown(ob ject sender, System.Windows. Forms.KeyEventA rgs
e)
{
if (e.KeyCode == Keys.Enter )
{
ConnString = "workstatio n id=HRV;packet size=4096;integ rated
security=SSPI;d ata source=HRV;pers ist security info=False;init ial
catalog=DVD Kolekcija";
bDb = new Db(ConnString);
grid.Refresh();
grid.Table = bDb.datasetDVD. Tables ["DVD"];
}
}

I put your code into my user control :

protected override bool IsInputKey(Keys keyData)
{
if (keyData==Keys. Enter) return true;
return base.IsInputKey (keyData);
}

Re: treeView keydown

This is how you must change your code :

namespace MonNameSpace {
public class MyUserControl : UserControl {
....
....
TreeView2 treeKolekcija;
....
....
....
private void InitializeCompo nent() {
...
...
this.treeKolekc ija = new TreeView2();
...
...
}
...
...
private void tree_KeyDown(ob ject sender,
System.Windows. Forms.KeyEventA rgs e) {
...
your code
...
}
...
...
}
class TreeView2:TreeV iew {
protected override bool IsInputKey(Keys keyData) {
if (keyData==Keys. Enter) return true;
return base.IsInputKey (keyData);
}
}
}

Of course, if you have already overloaded TreeView Class, do not extend
TreeView2 from TreeView but from your own TreeView class.

Hope it helps...
If it does not, I would send you a complete example.
